Description

The sash lock that a kind of single face is installed

Technical field

The utility model relates to the alumium alloy door and window of horizontal folding with locking, particularly Suo mounting structure.

Background technology

Traditional alumium alloy door and window slide window lock, lock body assembly in the aluminum window frame section, employing be two-sided location, fastening.I.e. one side perforate at window frame profile embeds lock body, open the clinch nut hole at the window frame profile another side, when sash lock was installed, inserting bolt was adjusted the lock body position, screw after making bolt and the clinch nut of another side docking, the shortcoming of this traditional structure is: 1, installing and locating difficulty, assembly trouble; 2, many, the increase processing cost of perforate operation on the window frame; 3, clinch nut is given prominence to, is exposed at the window frame back side, influences the attractive in appearance of window frame.

Summary of the invention

The purpose of this utility model is the defective mounting that overcomes traditional sash lock, propose a kind of simple in structure, assembly is simple and convenient, does not influence the sash lock that the single face of door and window outward appearance is installed again.

The purpose of this utility model is achieved by the following technical solution: the sash lock that a kind of single face is installed, include lock body, lock hook, sash lock panel, fastening bolt, sash lock panel, the corresponding cover of lock body are embedded on the installing hole of window frame panel, the sash lock panel has the fastener hole that allows fastening bolt pass in two ends up and down, the back side of fastener hole, the upper and lower of lock body are respectively equipped with square clamp nut, square clamp nut is corresponding with fastening bolt to spin, when fastening bolt screwed, the lower edge was clamped between square clamp nut and the sash lock panel on the installing hole of window frame panel.Further, for ease of the installation that is nested of sash lock and window frame panel, the installing hole of window frame panel top also has the fastening slotted eye of the guiding that cooperates with fastening bolt.

Such structure adopts the square clamp nut of self-locking, has tangible advantage: 1, the assembly of sash lock, fasteningly only just can finish in the one side of window frame, easy for installation; 2, the window frame back side need not perforate, and manufacturing procedure reduces, and outward appearance is complete, attractive in appearance; But 3, the just assembly sash lock that tights a bolt need not be to the hole, and is simple to operate.
